Yes, ISIS.

Via Daily Caller:

ISIS banned the wearing of burkas at security sites in a northern Iraqi city in spite of previously demanding women wear the garment, Iran Front Page reported.

According to a report by Al Alam News, translated by IFP, ISIS mandated under brutal enforcement that women in their territory in Iraq and Syria wear a burqa and niqab in the last two years. But this changed, a source told IFP, when a fully veiled woman killed several ISIS commanders and members in the last few months.
